Fix subtitles that are out of sync
There are two kinds of out-of-sync subtitles, and both are easy to fix once you know which one you have.

Which problem do you have?
If every line is early or late by the same amount, the subtitles just need moving. That happens when a version of the film has a different intro.
If they start right but drift further out, they were made for a different frame rate, usually 25 against 23.976 frames per second. They need stretching instead.

Key benefits
- Both fixesMove by seconds, and fix frame rates, in one go.
- Any formatSRT, VTT, ASS and SBV, kept in the same format.
- Accents fixed tooOlder subtitle files are read correctly and saved as UTF-8.
How to fix them
- Note when a line is spoken in the video, and when it appears in the subtitles.
- Open the subtitle file in Fix subtitle timing.
- Type the difference in seconds (a minus number to show subtitles earlier), or choose the two frame rates if they drift.
- Press Convert and save the fixed file next to your video.
Tips
- Check a line near the start and one near the end: same gap means move, growing gap means frame rate.
- Many players can shift subtitles too, but only until you close them; fixing the file makes it permanent.
- Keep the same file name as the video so players pick it up automatically.

Questions
Which frame rates should I pick?
Drifting later through the film usually means made for 25 and played at 23.976. Try that first, or the other way round if they drift earlier.
Will it change the text?
No, only the times, unless you choose to remove formatting or sound descriptions.
Can I fix several files?
Yes. Open them together; each keeps its own format.
